title: [Deep vasculitis].
abstract: The author gives a definition of the term "vasculitis". Histopathological modifications are the result of a disturbance in the barrier function exerted by the vascular endothelium. The disturbances observed are characterized by piles of endothelial or intimal debris associated with a perivascular inflammatory reaction of the connective tissue and the appearance of a resorption granuloma. Whether superficial or deep, vasculitis can become "nodular" in appearance and is then characterized by "nodules" or "patches". In order to implement aetiological treatment, it is necessary to look for the causative agent: an infectious, drug or bacterial allergen, or hypertension is frequently involved.
